What plugs in here?

[92470]

I was doing a little maintenance under the hood of my 87' V10 today and noticed a few things that I was unsure about. If someone can tell me what, or if anything is supposed to plug into the following connectors, I would really appreciate it. I have the factory service manual, but can't figure out if something is disconnected under my hood, or it is supposed to be that way. My truck runs, but still wondering. It's also a 5.7 350. I have attached pics for reference. if someone can tell me what they are, and if if they are unplugged, what they are supposed to go into, I would appreciate it. Thanks

Note the first one is behind the air cleaner and is a black connector with a white wire that is not connected to anything. Second one is on the firewall and is a black connector with a red wire, again not connected to anything. I hope I posted the pictures correctly.
